Molecular Weight: 381.54

MolecularStructure:

Appearance: Colorless or pale yellow oil; white powder

Category: Organic Intermediate

Application scenarios

1. Pharmaceutical Intermediates

These intermediates serve as key building blocks for the synthesis of more complex chiral drugs, particularly those containing a β-lactam core structure (such as certain antibiotics and protease inhibitors). Search results highlight the use of similar azacyclobutanone intermediates for the synthesis of chiral drug precursors.

2. Chiral Synthetons

Their (3R,4S) absolute configuration allows for asymmetric synthesis as starting materials or intermediates for introducing specific chiral centers.

3. Chemical Synthesis Research

In organic chemistry methodology research, they may serve as model substrates for developing novel synthetic methods (such as new cyclization, functional group transformation, or protecting group strategies).
